AI agents call peekStackElement to retrieve information from ThinkMem without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool peeks at the top element of a stack-mode ListMemory without modifying it. It is a pure read/query operation with no side effects, making it Read category with low severity.
From the tool's definition 查看栈模式ListMemory的顶部元素，用于预览栈顶状态 — 'peek' and '查看' (view/inspect) and '预览' (preview) confirm read-only access
Documented attack patterns abuse exactly the kind of access peekStackElement gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and ThinkMem, and nothing reaches the server without passing your rules. This is the rule we recommend for peekStackElement:
{
"version": "1",
"default": "deny",
"tools": {
"peekStackElement": {}
}
}peekStackElement is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the ThinkMem MCP server in PolicyLayer and add a rule for peekStackElement: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches ThinkMem. Nothing to install.
peekStackElement is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the peekStackElement rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for peekStackElement. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
peekStackElement is provided by the ThinkMem MCP server (rickonono3/thinkmem). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from ThinkMem, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
